Abstract

Fremgangsmåte for hurtig inversjon av data fra en kontrollert kilde elektromagnetisk undersøkelse av et område i undergrunnen. Utvalgte (51) felles mottaker eller felles kildesamlinger av data omdannes til komposittsamlinger (52) ved å summere deres data. Hver komposittsamling fremadmodelleres (i inversjonsprosessen) med multiple aktive kildelokasjoner (53) beregningstiden reduseres proporsjonalt med forholdet mellom det totale antall komposittsamlinger med det totale antall opprinnelige felles mottakere eller felles kildesamlinger. Dataene kan fasekodes for å hindre kansellering av data. Fremgangsmåter for å utbedre tap av fjern forskyvning informasjon ved overlapp av data i summeringsprosessen blir beskrevet.Method for rapid inversion of data from a controlled source electromagnetic survey of a subsurface area. Selected (51) common receivers or shared source collections of data are converted to composite collections (52) by summing their data. Each composite collection forward modeled (in the inversion process) with multiple active source locations (53) computing time is proportionally reduced by the ratio of the total number of composite collections to the total number of original common recipients or common source collections. The data can be phase coded to prevent data cancellation. Procedures for correcting loss of distant offset information by overlapping data in the summation process are described.
